Two leading ladies of the big screen – Amanda Seyfried and Zoe Saldana – and one of the small screen's fiercest fashionistas, Leighton Meester, top Glamour magazine's "50 Most Glamorous Women of 2010" list, the mag's third annual countdown.

The Hollywood lovelies each get their own cover for the magazine's April issue, where they dish about style and their glam lives – but "Dear John" star Amanda Seyfried said she doesn't play into the material side of Hollywood.

"Maybe people [in Hollywood] wear really nice clothes, and they drive really nice cars—but that doesn't make me comfortable. And if I'm not comfortable, it won't be part of my life," she told the mag. "A smoky eye and nice hair are not going to make my night any easier… I have to feel good on the inside to look glamorous."

The actress also revealed that she's not the most outgoing starlet.

"It's sad, actually," she told the mag. "Because my anxiety keeps me from enjoying things as much as I should at this age."

"Avatar" and "Star Trek" beauty Zoe Saldana, on the other hand, is enjoying her fabulous time in the spotlight.

"I want to have more sex, travel more, drink more wine and love life," she said. "I love women. I worship women. Don't want to be any other woman but myself."

And when it comes to style inspiration, "Gossip Girl's" Leighton Meester looks to the leading ladies of music – plus her sex life and her BFFs.

As for trading her glam life for the married life, Leighton, who is dating fellow "Gossip Girl" star Sebastian Stan, said she's not ready to settle down just yet.

"If [marriage] was important to somebody I loved, maybe I'd think about it, but I don't think that I'm the type. It's not for me," she said. "I wouldn't mind living together. [But] eventually I'll have to get a separate house for my shoes!"
